The magazine was launched in 1989 when its predecessor, the short-lived ST/Amiga Format was split into two separate publications. Most of the staff went on to work at ST Format with Amiga Format essentially being a whole new magazine.
Latterly, the magazine was kept alive by enthusiastic freelancers such as Frank Charlton and Andy Curtis, as well as dedicated staff writers and editors such as Clive Parker and Nick Peers.
ST Format continued publication until 1996, when production of the Atari ST and Falcon computers was all but over. The final issue was published in September 1996, and was the eighty-sixth issue of the magazine. Fan sites for the magazine still exist on the internet, some featuring archives of features from the magazines.
